无约束优化问题的修正PRP共轭梯度法
A Modified PRP Conjugate Gradient Algorithm for Unconstrained Optimization Problems
摘要
Abstract
A new conjugate gradient algorithm is presented by combining the Newton and the PRP conjugate gradient methods, which can be seen as the modification of PRP method. The new method take both available gradient and the part second-order information.Our algorithm is shown to be global convergent under some assumptions. Numerical results are also reported.关键词
